Swine researchers find UV light may inactivate PRRS virus

Study conducted on common materials found on pig farms

According to researchers at the University of Minnesota College of Veterinary Medicine's Swine Disease Eradication Center, ultraviolet light may have the ability to inactivate the porcine reproductive and respiratory syndrome virus.

Ultraviolet light is already known for neutralizing viruses, bacteria and parasites by disrupting the nucleic acid and preventing replication. The study focused on the concentration and viability of PRRSV on surfaces and materials commonly encountered on swine farms, including wood, plastic, latex, rubber, styrofoam, metal, leather, cloth, concrete, cardboard, glass and paper.

The researchers' results suggest that UV(254) is an effective means to inactivate PRRSV on commonly encountered farm surfaces and materials and inactivation can be accomplished following 10 minutes of exposure.
